The water episode will have done no lasting damage IF it was thoroughly drained at the time. If water was still in there somewhere you'd see 'mayonnaise' floating inside the rad cap.
Thanks Chris. 5-7lbs is fine for a warmed up engine but not at start up from cold. This lack of higher pressure when cold made me think maybe the pump is at fault. There's no mayo in the rad and there's no obvious grey emulsion in the oil. Only the frothing, which subsides after the engine is turned off and left for a while.
